Dr. Semyon Tsynkov

Overview: Dr. Semyon Tsynkov is Associate Director of the Center for Research in Scientific Computation at North Carolina State University where he is also a Professor of Mathematics.

Dr. Tsynkov received his Ph.D. and Doctor of Science Degree (Habilitation) in Computational Mathematics from the Russian Academy of Sciences (Moscow, Russia) in 1992 and 2004, respectively. His research areas include numerical solution of partial differential equations with applications to fluid flows and wave propagation in acoustics, electromagnetism, optics, and plasma, as well as inverse problems arising in active control of sound and remote sensing, in particular, synthetic aperture radar imaging.
